TWILERED EAMES, OF EVANSVILLE, INDIANA, ASSIGNOE T() THE EVANS- VILLEPUMP AND PIPE COMPANY, OE SAME PLACE.

PUVIP.

SPECIFICATION forming part of Letters Patent No. 302,626, dated July 29,1884.

Application filed March H, 1884. (No model.)

iro all whom t may concern/ Be it known that I, WILFRED EnMns, a citizenof the United States, residing at Evansville, in the county ofVanderburg and State of Indiana, have invented certain new and usefulImprovements in Combined Lift and Force Pumps, of which the following isa specification, reference being had therein to the accompanyingdrawings.

My invention has relation to lift or force pumps 5 and the object is toconstruct a simple and inexpensive form 0f pumps adapted for general usefor wells and cisterns, that will be easily operated, and at the sametime very durable; and to these ends the novelty consists in theconstruction, arrangement, and combination of parts, as will behereinafter more fully described, and particularly pointed out in theclaims.

In the accompanying drawings similar letters of reference indicate thesame parts of the invention.

Figure l is a sectional elevation of the` cylinders and theirconnections, and Fig.' 2 is a 2 5 side elevation of my improved pump asit appears set in position and ready for operation.

A is the standard, and it is provided at its top with the usual form ofgoose-neck, B, having discharge-spout C.

D is the bracket-support, in which the handle E is mounted. v

F is a brace secured to the platform G, so as to support the upper partof the standard in a rigid manner.

To the lower end of the standard A is secured a T-iitting, H, and I is ashort pipe eX- tending frorn the bottom of the T-iitting H to the hollowarm K of the pump base L.

-ro This short pipe I is closed at its upper end, and there is noconnection between it and the standard A.

M is the upper and N the lower pump-cylinders, and they are cast in onepiece with the side outlet-connection, O.

a d are lugs cast, one on each `side of the lower cylinder, N, near itsbase, and b b are similar lugs on the base L, through which pass bolts@,iirmly securing the double cylinders 5o to said pump-base.

P isa groove on the outside of the cylinders,

in which set the stirrups or link R, extending around said cylinders andthe T-fitting II, and when the taper key or wedge S is inserted anddriven home the cylinders and fitting are iirmly bound together, and atight joint made between said fitting and the cylinder outletconnection0.

The pump-base Lis cast in one piece with hollow arm K and lug d, andtothe bottom of 6o this base is secured the suction-pipe T.

U is the foot-valve, cut from a single piece of leather or rubber, andits periphery forms the packing-ring u, while the valve itself sea-tsupon the face of the base L.

V is the piston-rod,- its upper end secured to the handle in the usualmanner, and its lower end is provided with pistons YV X, workin-g in thecylinders M and N.

Y is a supporting-rod extending from the 7o lug d on the pump-base L tothe platform-plate Z, and this rod Y and standard A serve to support thepump-cylinders in a vertical position at any depth in the well.

Theshort pipe I being closed at its top and open at its lower end, so asto be in connection with the hollow arm K, its interior forms avacuum-chamber, Q', which, being filled with air when the pumpis firststarted, is exhausted by the first few strokes ofthe pistons, and So las the water raises in the suction-pipe and through the pump-base andhollow arm, so as to ll said chamber, the pump is now ready for use.

I have shown the short pipe I closed at the top to form thevacuum-chamber; but Ido not wish to be understood as limiting myself tothis exact construction, as it is obvious that the same result will beattained if there be a partition cast inthe T-i-tting II just above 9othe end of said pipe I.

By removing the bolts c and key S the cylinders M N may be removed andaccess had to the various working parts of the pump Without interferingwith the standard A, suction-pipe T, base L, or supporting-rod Y; and itwill thus be seen that it is only a few moments7 work to repair thevalves orpump when occasion requires, and the operation is so simplethat skilled labor is dispensed with Ico and any person may perform it.Having thus fully described my invention,

l what Iy claim as new and useful, and desire to secure by LettersPatent of the United States, 1s-

l. The eo1nbination,with the cylinders M N and T-itting H, ofthe stirrupR and taper key S, as and for the purpose set forth.

2. The combination, with the Cylinders M N, having grooye l?, und theT-itting H, of the stirrup R and key S, as set forth.

3. The combination, with the cylinders M N, groove P, and outlet 0,2111constructed of one piece, as described, of the T-tting H, stirrup R, andkey Sr, as set forth.

4. The combination, With the cylinders M N, having lugs a, the base L,having lugs b d,

and hollow arm K, of the supporting-rod Y,

piston-rod V, and. vacuum-chamber I, as and for the purpose set forth. A

5. The combination, with the Cylinders M N, base L, having lug d, andhollow arm K, of the supporting-rod Y and standard A, tting` H, andVacuum-chamber I, arranged. in a vertical line, as und for the purposeset forth.

In testimony whereof I affix my signature in presence of two Witnesses.

VILFRED EAMES.
